MET Calculator
Calculate MET, calories, MET-minutes and VO2 from an activity, manual MET value or oxygen uptake input.
ACSM intensity scale
Intensity classification from the American College of Sports Medicine. The same MET can feel different for a beginner and a trained athlete.
Weekly activity target
600 MET-min/week is a lower reference for adults without contraindications; 1500 MET-min/week is a higher target, not a universal prescription.
Calculate MET-minutes and calories
MET intent is usually educational and practical: users want to convert an activity intensity into calories, VO2 and weekly activity volume.
Weekly activity volume can be compared by adding MET-minutes across sessions.
